The truth is he doesn't know much about himself sober so he needs to figure that part out. Living his life and meeting his responsibilities as a sober person will be very hard for him for some time. If you do have a future, him being able to be independent and sober would be the best thing.
All you can do is respect where he is at right now but something tells me it may shift and change so just take care of yourself until he figures out his life.
